The invention relates to a method and a device for introducing and/or adding non-dry-powder additive materials and/or coating materials with a liquid, solid, semi-solid, or paste-like consistency or in suspended or emulsified form, for example, peroxides, fats, waxes, IV improvers, polymers, or similar materials, to an existing lumpy or particulate material which is moved and mixed, and optionally warmed and reduced to small pieces in a receptacle and/or compressor (1), said material being in particular polymer particles and/or flakes, wood fibers, paper cuttings, or similar materials. According to the invention, the additive material is introduced below the level of the material and/or material particles already in the receptacle (1).

La présente invention concerne un procédé et un dispositif d'introduction ou d'ajout d'additifs pulvérulents non secs ou de produits d'enduction de consistance liquide, solide, semi-solide ou pâteuse ou sous la forme de suspension ou d'émulsion tels que des peroxydes, des graisses, des cires, des améliorants IV, des polymères ou similaires, à une matière broyée, fragmentaire ou particulaire, en mouvement, mélangée et éventuellement chauffée dans un réceptacle ou un compresseur de coupe (1), en particulier des particules ou des flocons de polymère, des fibres de bois, des rognures de papier ou similaires. L'invention prévoit que les additifs soient ajoutés sous le niveau de la matière ou des particules de matière contenues dans le réceptacle (1).
